The problem with diets is that they don't work - not in the long term, anyway. Yes, you can lose weight initially, especially with a drastic decrease in calories, but the likelihood is that you will soon return to your old eating habits and regain any weight lost. After working with thousands of clients, I know that success only happens when a programme is enjoyable and sustainable.

This sweet potato and smoked haddock tortilla tastes incredible. Healthy fish and eggs cooked together with tasty tomatoes, what's not to like? A good idea is to double up the quantities in this recipe, so you can prep like a boss and stock up the fridge up for the week ahead.
